Figs 132–134, 186 Diagnosis. Ecnomina wirromandiis distinguished from other species in the group, by the inferior appendages, which in ventral view have no disto-lateral excision, and the apices are widely separated by a U-shaped excision. Description. Head, body and wings brown, abdomen paler ventrally; wings similar to E. legula( Fig. 3). Forewing length about 2.9–3.0 times width: male 3.2–3.6 mm; female 3.7–4.0 mm. Forewing fork 2 relatively long, sessile, length about 1.3–1.4 times length of fork 3; fork 3 relatively long, with short footstalk, fork greater than 3–4 times length footstalk, footstalk length about 1.4 times length cross-vein m, r-m and m nearly contiguous at footstalk, r-m and m separated by about 0.6–0.7 times length of cross-vein m; fork 4 shorter than fork 3; fork 5 long, length about 1.9 times length of fork 4. Hindwing length about 3.1–3.2 times width, fork 2 sessile, length about 1.7 times length of fork 3. Male. Tergum X membranous, fused basally, with two pairs of dorsal processes, a robust mesal pair and a slender pair laterally ( Fig. 134), a ventral process also present. Superior appendages in lateral view, robust, broad in basal half, tapered in distal half, length about twice width ( Fig. 132); in dorsal view, length about 4 times width, with several spines in distal third, dilated slightly distally ( Fig. 134). Phallus down turned and dilated apically with dorso-apical process ( Fig. 132). Inferior appendages short, dorso-ventrally flattened, broad basally; in ventral view, fused, length about same as width, rounded slightly laterally, tapered slightly distally with apices widely separated by U-shaped excision ( Fig. 133); in lateral view, robust basally, upturned and slender distally ( Fig. 132). Female. Genitalia with a single short, robust mesal process, slightly tapered apically on sternite VIII; segment IX relatively long, tapered slightly distally, segment X relatively short and segments IX and X relatively slender ( Fig. 186).
